To find the area of fabric in square yards to cover both sides of the cushions.
Answer to Problem 47SPR
Total area of fabric
Explanation of Solution
Given Information:
There are seven congruent circular cushion with a diameter of 12 inches around a center cushion with a diameter of 20 inches as shown below:
An extra 3 inches of fabric should be addedto the fabric around each cushion.
Formula used:
Area of
Diameter of centre cushion
Radius of centre cushion
∴ Area of centre cushion
Diameter of each of seven circular cushions = 12 inches
Radius of each of seven circular cushions
∴ Area of each of seven circular cushions
There are seven congruent smaller cushions and one central cushion. Each cushion has 2 circular sides (which is the fabric on back side).
The total area of fabric = 7 (2 times the area of smaller cushion) + (2 times the area of central cushion)
To convert sq. in to square Yards divide by
